SClSSORS-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 488,043, dated December13, 1892. Application filed April 18, 1892. SerialNo. 429,591. (Nomodel.)

To all whom it may concern.-

Be it known that I, EARL A. THISSELL, a citizen of the United States ofAmerica, residing at Northampton, (Florence,) in the county of Hampshireand State of Massachusetts, have invented certain new and usefulImprovements in ScissorsSharpeners, of which the following is aspecification, reference being had therein to the accompanyingdrawings.

My invention has for its object to provide a simple and effectiveedged-tool sharpener, particularly for scissors, and designed for use inthe household and by persons unskilled in the handling of toolsgenerally. In providing a device of this kind it is desirable to make itinexpensive in order that it can be placed on the market at a smallcost. It is also desirable to present the article in complete anddurable form, which will render unnecessary any technical knowledge onthe part of the user and will not require any adjustment or setting ofparts.

In the accompanying drawings, Figure 1 represents a side view, and Fig.2 a section transversely through the head of the sharpener.

The implement consists of a head 1 of substantially-cylindrical form,having in its surface a peripheral groove, the bottom of which is curvedandis provided with file-like serrations extending diagonally across thegroove in sinuous form. To one side of the head and extending laterallytherefrom is arranged the handle 2, having an enlarged end and a reducedportion adjacent to the head, the said handle being rounded and inconvenient form to be retained in the fingers.

The whole device is formed in one piece and is complete in itself readyfor use, requiring no manipulation or adjustment of parts nor anyparticular knowledge of the use of sharpening-tools other than thatpossessed by the ordinary unskilled person.

In the use of the device it is my purpose that both blades of thescissors shall be sharpened at one operation, and it will be obviousthat the form of the head with the curved groove therein is especiallyadapted for operating upon the reversely inclined or beveled edges ofthe blades simultaneously when interposed between them and moved backand forth toward and from the pivot of the scissors, it being understoodthat the user applies pressure to the two blades of the scissors bygrasping the handles thereof, and thus keeps the blades in firm contactwith the file'surface of the sharpener, the scissors being opened andclosed as the sharpening implement is moved toward and from the pivot.The implement is held in the hand of the user at one side of thescissors. It will be observed that by reason of the curved form of thegroove and from the fact that the file-surface extends entirely fromside to side thereof that the sharpener is adapted to receive scissorsof various sizes whose edges are beveled at different angles and thatthe working surface of the sharpener extends entirely across thecutting-edge of the blade.

While it is particularly advantageous to form the entire device in onepiece, it will be understood that I do not confine myself to thisconstruction. It is especially desirable, however, that the head beformed in one piece to present the double file-surface complete initself.

I claim 1. A scissors-sharpener comprising a cylin drical head having aperipheral groove with a sharpening-surface and a handle extendinglaterally from the head and in line with the axis thereof, substantiallyas described.

2. A scissorssharpener comprising a cylindrical head having a peripheralgroove with a sharpening-surface and ahandle extending laterally fromthe side of the head and in line with the axis thereof, said handlebeing an integral extension of the head, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
